Read the following statements:
$A.$ Variation at genetic level arises due to mutations.
$B.$ The technique of $DNA$ fingerprinting was initially developed by Alec Jeffreys.

Select the correct sequence for the process of $\text{VNTR}$ technique.
$X =$ Hybridisation using labelled $\text{VNTR}$ probe
$Y =$ Digestion of $\text{DNA}$ by restriction endonucleases
$Z =$ Transferring (blotting) of separated $\text{DNA}$ fragments to synthetic membrane,such as nitrocellulose

What is $DNA$ fingerprinting?

Which technique is required to study the binding of specific proteins to $DNA$ sequences?

Which of the following sequences do not code for any polypeptide?

Some of the steps of $DNA$ fingerprinting are given below. Identify the correct sequence from the options given.
$A$. Electrophoresis of $DNA$ fragments
$B$. Hybridisation with $DNA$ probe
$C$. Digestion of $DNA$ by $RENS$
$D$. Autoradiography
$E$. Blotting of $DNA$ fragments to nitrocellulose membrane
